"Technically, yes, you do weigh less after farting. When you expel gas from your body, you're removing mass, which means your weight decreases. However - and this is a big however - the amount is so incredibly tiny that it's essentially meaningless for weight loss purposes."
Burping and farting are tiny, but if we're talking gasses and changing weight, the vast majority of the mass you lose from fat when you lose weight actually comes out in your breath.
OP's concept seemed to be about buoyancy. In the same way that a hot air balloon weighs more when it releases hot gas, so too should a human weigh more when they release hot gas. So the question comes down to, is the decrease of buoyancy force more or less than the weight of the ejected gas molecules?
For weight loss purposes, you actually lose the weight by breathing. O2 in C02 out. You're constantly shedding carbon. Does breath count as warm gaseous emissions?
I guess warm breath rises, you can see it in winter when your breath is visible.
However, co2 is not present as a gas in your body, but bound to hemoglobin, so I think it only becomes a gas again in your lungs. Same as farts only forming "outside" your body in your intestines.

Meaningless? I don't know mate, I always feel lighter after a good fart.

Well it depends on the pressure the gases are being kept under. Higher pressure and you gain buoyancy. Low pressure and you lose it.

Damn, bro came with receipts! But think about it, OP... if you expel even a tiny bt of something, you will have lost it.

This fella farts the facts! 👍

Did you ask this just to setup your reply??
Either way, brilliant.

Maybe..
Happy Fart Day!

First one to record themselves farting so hard the scale changes, wins!

Does the warm carbon dioxide and other warm gaseous compounds sink or float?

Methane is lighter than air
